nosatn commented 3 months ago

When I try to run this little script on a raspberry pi

#!/usr/bin/python3

from dydx3 import Client
from web3 import Web3

#
# Access public API endpoints.
#
public_client = Client(
    host='http://localhost:8080',
)
public_client.public.get_markets()

this error occurs
